` AUGUST A. Msmvrnnoitizens of the United following is a specification.P

States, and residents of the city of Chicago; county `of Cook, and State of Illinois, have invented certain new and useful improvements in Ironing-Machines, of which the Qur invention relates to improvements in ironing machines and has for its object the production of a device of this character which will be especially adapted for home use or in private lau'ndries.

A further object .of our invention is 'the production of a machineOf the character mentioned which will beoi:` durable and economical construction and eilicient in use.

Otherv objects will appear hereinafter.

W'iththese objects in view, our invention consists in the combinations and arrangements of parts vall as will be hereinafter described and claimed.

Our invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, ,y

Figure l is a partial sectional side elevation of an ironing machine embodying our invention, Fig. 2 is a partial sectional side elevation of one of the levers whereby the ironing rollers may be moved outwardly through foot power, Fig. 3 is a front elevation of the upper end portion of the lever shown inFig. 2, Fig. 4c is a front elevation of the ironing machine, the central portion thereof being broken out and one of the ironing rollers bei-ng omitted as well as the springs and spring housings cooperating "therewith in order to better illustrate the construction, Fig. 5 is a top plan view of the construction shown in Fig. 4C, the hand screws cooperating with the ironing roller springs being show-n in section, Fig. G is a side elevation of the segmental ironing meniber of the ironing machine detached, the central portion thereof beinof broken out, Fig. 7 is an end elevation o? said ironing member, and Figs. 8 and S) are a front view and sido elevatlon respectively of one of the supporting members coperating with said segmental ironing member.

lhe preferred form of construction, as illustrated `in the drawings comprises a frameconsisting of two spaced members 1 which are rigidly' connected luy-bars 2. Ar

ranged between the zipper ends'oi the frame members i is a segmental ironing member 3 the respective ends of which are secured to supporting members The attachment of said ironing member to the supporting members 4 is effected by means of screws the inner ends or heads of which engage slotted lugs 5 provided at the open ends oi said ironing member. The su porting members ll. are fulcrumed at if to t e frame members l so as to permit of oscillatory movement of said ironing member 3. The center of currature of the onveyr side of the ironing member 3 is coincident with the center of oscillation of said ironing member and said surface is smooth and polished so as to permit of the ready sliding thereover of the ai ticles ironed.

The ironing member 3 is heated during operation of the ironing machine by means of a gas pipe 6 which is arranged therein, the upper side of said pine being perforated for the escape of gas. The end pieces t are provided with elongated arenal slots 'i to accommodate the ends of pipe 6 in order 'fili to permit'of rocking movement of the ironing member 8, the ends of said pipe being rigidly secured in the ira-me members 1. vOno end of the pipe 6 is connected with any suitable source of fuel supply,- a suitable valve 8 being provided for governing the flow oil gas to said pipe. The ironing member 3 normally held at one terminal of its rocking movement. against stops 9 which are formed at the inner sides of the frame men'ihers i). ly means oi a helical tension spring l0, stops 9" serving to limit the recit` ing movement of said ironing member downwardly. The stops 9" are formed at the inner sides of arms l2 which are arranged at the inner sides of the frame members l between the latter and the respective ends of the ironing member El, the lower ends of said arms 12 being fulcrumed at 13 to said frame members l. Arranged between the upper ends of the arms l2 are the padded ironing rollers 14 of the ironing machine, said rollers when the device is in use rotating in contact with the convex side orp the ironing member 3, the amplitude of oscillation of said ironing member being such that the same is constantly in registration with said roll ers. The journals l5 of the rollers le are mounted in bearing blocks 16 `which are slidiet formed at the upper or free ends of the arms 12. Helical compression springs 18 coperate with the bearing blocks 16 for normally v holdingthe rollers 14 in contact with the the arms l2 are arms 21 which are provided at their lower ends with hooks 22 adapted to engage under lugs 23 formed at the inner sides of the frame members l to releasably lock the arms 12 against rocking movement and hence to hold the rollers 14 in contact with the ironing member 3. The upper ends of the arms 21 are connected by means of a bar 24 which serves in the capacity of a handle adapted for engagement during operation of the machine to etl'ect oscillation of the locking members 21 in locking or unlocking the arms 12 carrying the rollers lll- A rod 25 rigidly connects the upper ends of the arms 12 in order-` to insure unisonous movement of said arms. v

Fnlcrumed upon the respective ends of the rod 25 adjacent the inner sides of the members 21 are arms 26 the lower ends 27 of which are pivotally connected with the upper ends of links 28, the lower ends of said i inks being pivoted at 29 to the frame members 1. iWith this arrangement, it will be seen, that a toggle will be constituted by each pair of cooperating members 27 and 28 and so that when the upper ends of the arms 2G are rocked, said toggles will be actnated to cause rocking of the arms 12 and hence movement of the rollers 14 into or out `of engagement with the ironing member 3. Inwardly projecting from the arms 21 are pins 3() which engage arenal elongated slots 31 formed in the upper ends of the arms 26. lith this arrangement, it will be seen, that an operative connection is established between tho arms 21 and 26 and so that in operation, upon forward osc'illation of the arms 21, the lower hooked ends 22 thereof will nrst be moved to inoperative position to release thel arms 12 whereupon oscillatory movement will be imparted to the arms 26 to canse straightening of the toggles constituted by the portions 27 and 28 and thereby effect rocking of the arms 12 to carry tbe rollers 14 out of engagement with the ironing member 3. By the employment of the slot-and-pin connection between the arms 2l and 26, during oscillation of the arm's 2l the' oscillatory movement which is imparted to the arms 26 by said arms 21, is delayed until the lower hooked ends 22 of the arms 21 have disengaged the lugs 23. With thi construction the unlocking and movement ofv thickness.

the padded rollers of the ironing machine ont of engagement with the heated ironing member may be effected With ease and eX- pedition and so that in the operation of the ironing machine, upon cessation of operation, said padded rollers may be readily and quickly moved to inoperative position to prevent scorching or burning of the padding of said rollers which otherwise results if permitted to remain in Contact With the heated ironing member.

Fulcrumed at 32 upon the inner sides of the frame members 1 are levers 33 provided at their upper ends With lugs 34 to which are secured curved bars 35. The bars 35 are adapted to contact with lugs 36 which are formed at the under sides of the bearing blocks 16, the arrangement being such, that, when the lower ends of levers 33 are rocked forwardly, the bars 35 Will be moved upwardly to cause movement of the rollers 14 ont of contact with the ironing member 3. The lower ends of the levers 33 are connected by a cross piece 37 Which is provided at its front edge with a medially positioned tongue 38 adapted to be engaged by the foot in order to cause operative rocking of the levers 33. One of the -bars 2 of the frame of the mangle is positioned in close proximity With the bar 37. so as to serve as a stop for the foot to determine the amplitude of operative movement of said bar 37 and hence rocking movement of the levers 33. The last described construction for effecting outward movement of the rollers 34 is designed for employment where the article, which it is desired tov iron, is of considerable In these cases it is difficult to start the article into the machine between the first roller 14 and the ironing member 3, and in order to facilitate this starting, during operation of the ironing machine, the levers 33 are operated by means of the foot pressing upon the tongue 38 to move the rollers 14 outwardly to a limited extent. vllor ordinary ironing, that is where the articles are not of great thick,.ss, this mechanism for moving the rollers outwardly will not be utilized.

The oscillatory mounting of the ironing member 3 is also to facilitate the starting of the articles to be ironed into the machine. By rockingly n'iounting the member 3 as mentioned, the latter, in starting an article through the ironing machine` will operate in the. Asame manner as a roller relative to the lil-st roller 14, rocking simultaneously with said roller to a limited extent in the starting of the article into the machine. The. diliicnlty experienced in starting an article. through the machine is occasioned by reason of the fact that ordinarily the edge ofan article is hemmed or double and therefore the end of the article is of greater thickness than the central portion thereof.

Therefore lin -ironing an article, the ygreatest pressure Willbe exerted at the,start,;but this pressure will'be relieved as the thinner cential poutionbf ,the article is reached vand so that :in It'he operation of .tbe machine the pressurenponthe ironing member 3 Will be reduced, after the article "has ,been started into the machine so as to permit of said ironing member bein rocked to its normal position under thein uence of spring 10.

The articles `which it is desired to iron aretirst--arranged upon the table 39 provided at theffront side of the machine, the upper side of said table being in substantially the same plane as the upper end of the ironing member 3. [A ,transversely extending rod 39 extends between the uppeoi` ends of thev arms 12 in close proximity with the upper end of the ironing member 3 to serve as a guard to prevent the lingers from being inserted between vthe first roller 14 and the ironin member 3. l

ers 14 are continuouslyrotated through the medium of gears provided at correspond-I ing ends of the .journals 15 ot said rolleis,v

saidgears meshing with an idler gear 41 mounted upon a stub shaft 41.

` outer side of one of the frame members 1.

drive the ironing machine as will be readily understood.
